Due to popular demand, all of our 2-piece, lightweight rotors will now come with black anodized rotor hats featuring Type 3, hard anodizing, the highest quality and hardest anodizing available for aluminum. This will make the rotor hats more resistant to fade and wear and will hide brake dust better. Due to popular, demand all lightweight rotor rings will also feature zinc plating. This high quality coating will slow the effects of corrosion and keep your rotor rings looking good through the winters.

IN STOCK AND READY TO SHIP!

FINALLY a low cost 325mm rear BBK (Big Brake Kit) for your B5 A4/S4. This is the BEST BBK we make to compliment our massive 350mm 6-piston Cayenne Caliper BBK for the front. Also this kit cannot be bought anywhere else since it is a custom rotor ring and hat that is not available from any other source. NOTE: A4 requires S4 rear calipers and caliper hangers to do this conversion. Use the drop down box on the ordering page to add these.

INSTALL NOTES: Due to the relocation of the rear caliper making it more outboard you are required to unsnap and release the plastic sleeve for the parking brake cable in the lower rear control arm. This is necessary to allow the cable to be pulled rearward some so it can reach the caliper without kinking or excessive stretching. (NOTE: This sleeve is usually brittle and prone to breaking and sometimes hard to release, so don't be worried if it breaks when performing this mod. As long as you can get it so the cable can be pulled rearward some you did the job correctly)

INCLUDES: 2 - JHM 2-piece Lightweight 325mm (12.8") Rear Rotors. 2 - Caliper adapter brackets CNC machined from 1/2" steel with a high quality zinc coating. (These are supplied to us by 034 Motorsport since we didn't see the need to make these as well and thus allowed us to get our BBK to market quicker with our larger B6-B7 S4 rear lightweight rotors) 4 - Caliper adapter bracket mount bolts (also supplied by 034 to us) 2 - DOT Stainless Brake Lines and adapters for B5 S4 calipers (also supplied by 034 to us) -Works with stock replacement B5 S4 rear brake pads. Such as OEM, Hawk, PBR, Mintex, Etc. We sell pads as well, if you don't see the ones you want contact us for details.

NOTE FOR B5 A4 OWNERS: You need these parts to complete the kit (new or used)

Outer ring specs: We worked closely with a race brake manufacturer that supplies many NASCAR racers and a couple major brake kit companies. Due to their expertise we chose to have them build us the outer rings to our specs to fit the B5 A4-S4. 12 attachment points for durability and strength.

Center hat specs: We CNC machine the Aluminum center hats in house based on their recommended materials and thicknesses for durability. 12 attachment points for durability and strength. We also engrave JHM in them in 3 locations equal from each other, it looks clean and doesn't jump out or look tacky.

Note - This brake upgrade will fit under most 18" inch or larger wheels. However, we have had customers inform us that this Rear BBK does not fit under VMR V710 Wheels in the 18 x 8.5, ET 35 configuration.
